However, daily mobility is severely restricted in patients with advanced COPD.Aim: We evaluated whether self-training at home using a bicycle ergometer with oxygen therapy is an effective therapeutic modality for COPD.Methods: We recruited 129 patients with advanced COPD. After an observation period, each patient was given a bicycle ergometer as per the advice of health care professionals. The patients were instructed to use the ergometer for 20 min each in the morning and afternoon, with oxygen therapy (2 L/min), and to maintain the maximum pulse rate at <110 beats/min. Before self-training was undertaken, each patient was examined to assess the effects of the training. We compared the data recorded after 6 months of self-training.Results: The subjects were divided into 2 groups: those using a bicycle ergometer (Group E) and those performing usual exercise (Group U). Group E was further divided into 2 groups: those showing good adherence (Group EG) and those showing poor adherence (Group EP). In Group EG, the mean age, BMI, FEV1%, and walking distance covered in 6 minutes were 72.3, 21.0, 44.2, and 423, respectively, whereas in Group EP, these values were 73.8, 21.1, 48.4, and 407, respectively. The walking distance significantly improved in Group EG. Continuance was 51.4%, and the major reasons for discontinuance were lumbago and arthralgia.Conclusions: Self-training using a bicycle ergometer with oxygen therapy might be useful in select subjects.
